#Java reflection get index of array code#
This class, which is composed of all static methods, acts as the go-between for our ColdFusion code and the Java array. To create and manipulate Java arrays, we are going to use the Java Array Reflection class,. Let's take a look at how this can be done in ColdFusion 7 first (so that we can then see how awesome ColdFusion 8 is). This is what gives us the ability easily resize arrays and store mixed data types within them.Ĭreating a Java array is insanely easy in ColdFusion 8 and somewhat burdensome in ColdFusion 7. The problem is that ColdFusion arrays are not Java arrays but are, in fact, some form of Vector List. Furthermore, attempting to pass a ColdFusion array into a method expecting a Java array will throw an error probably telling you that no such method exists. I have seen examples of this, but just wanted to walk through it so that I could fully understand how it works.Īnyone who has ever had to pass a Java array into a method has quickly come to find out that a ColdFusion array is not a Java array. NOTE: This post is not so much for other people, but rather more for myself as a lookup.
